Things I liked: Fantastic fit & finish! Accurate and well balanced. It's really a great pistol at an affordable price!

Things I would have changed: Nothing I can think of so far. Perhaps an option for the large grip although the medium does fit my 92 mm hand pretty well.

What others should know: Although not pictured my pistol did come with the trigger guard. It's attached via a supplied screw.

Things I liked: After a long time of Brazilian customs clearance, my Hammerli AP20 PRO, got here. Beautiful air gun, very well finished. Unhappily it came without the front sight and the screw that holds in the place, most likely caused by the handling. No problem! I know that Pyramid Air will sell another one to me.

Things I would have changed: I wouldn't change anything...

What others should know: I didn't rate Accuracy, because I didn't shot yet.

  • Thomas from USA asked:

    is this imported by UMAREX?

    • John from USA asked:

      Why does the Hammerli say Walther all over it?

      • David from USA:

        Hammerli is a very old company dating back to 1863. But all good things come to an end or evolve. In 2006 Hammerli was taken over by Walther. As such Walther became the parent company. Unfortunately, with the takeover, all of the Hammerli weapons from the original company ceased to be supported. That being said, Walther is also a very reputable company. While I have not had the pleasure of trying one of the newer Hammerli guns, I am confident they are a quality product worthy of either the Hammerli or Walther brand.
